Battle of the Rare Earth Magnets

Neodymium Iron Boron NdFeB (i.e. Neodymium) and Samarium Cobalt SmCo are both ultra-strong rare-earth permanent magnets.  Both are brittle in nature and subject to catastrophic damage if subject to severe impact (i.e. dropping).  However, that is where the similarity ends and, when selecting a magnet material for a specific application, our design engineers assess each…

Magnets to NASA

Bunting is thrilled to have been selected as the supplier of high specification grain boundary diffused Neodymium Iron Boron (NdFeB) Magnets for a NASA project. Grain Boundary Diffusion (GBD) technology enables the heavy rare earth element Dysprosium to diffuse from the surface of a grain around all of the grains boundaries.  Dysprosium is added to Neodymium…
